To `all whom, it may concern:

Be it known that 1, GEORGE WARRINGTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

It is the object of my invention to provide means for the thorough lubrication of bearings, and particularly such bearings as are exposed to the influence of low temperatures. An instance of this kind is met with in the construction and operation of snow-plows, in which an excavator is projected from the front of a car, the excavator consisting of an auger carried upon the end of a rotating shaft mounted in bearings longitudinally of the car. These bearings, and particularly the one nearest the auger, are so exposed that ordinary means of lubrication have failed to give-sat-` isfaction, the lubricant being congealed before it reaches the shaft-bearing. A further diiiiculty met with in the lubrication of the auger-shaft bearing in snow-plows is that of conveying the lubricant to the shaft-bearing p and at. the same time provide for operating a fan for the delivery of the snow on either side of the track. I provide an annular chamber from whichV the live steam for heating the bearing is supplied, while the fan may be run in either direction. `1

To overcome the difficulties above pointed out, I provide a pipe through the hollow of which the lubricant is conducted to the bearing, and this pipe is contained within a second pipe of larger diameter concentrically placed with reference to the first, and furnishing therewith an annular chamber into whichV live steam is introduced, and thereby the oil-pipe is kept warm and the fluidity of' j the lubricant maintained even at a temperature below freezing. I also provide steamways, whereby the entire bearing is kept warmed.

In the accompanying drawings I have illusn trated a snow-plow to the main shaft of which my means oflubrication are applied.

In said drawings, Figure 1 is an elevation, partly in section, of the front end of a snowplow car with a rotatable augershaft, the bearings whereof and asleeve forl rotating the fan are shown in section. Fig. 2 is a side ele- Serial No. 332,527. (No model.)v

vation of a portion of said shaft, the bearings whereof are in Vertical section. Fig. 3 is a transverse sectional view of the bearing at the forward end ofthe shaft, showing the ducts or channels in the face thereof for the distribution 4of the steam. Fig. 4 is a longitudinal sectional elevation ofthe same bearing, showing the oil and steam pipes in vertical section on line 5 .5, Fig. 1. Fig.,5 is a transverse section through the second bearing from the auger with the elbow of a steampipe in section. Fig. 6 is a longitudinal section of the same. Fig. 7 is a transverse vertical section of the shaft -bearing and the sleeve, whereby the fan is adapted to be rotated inl either direction; and Fig. 8 is an elevation of the same parts, partly in section.

In the drawings, 9 represents a portion of of the carwhich is .adapted to support a snowsteam=pipe having suitable connection with the'steam-supply and the oil-pipe being supplied from a cup, as 17, located, preferably, at some distance from the bearing, so as to be out of the iniluence of the low temperature to which the latter is subjected.

18 represents a second bearing, (shown in Figs. 5 and 6,) and in all respects similar to the one just described, except that the oil-pipe is omitted, oil being'supplied to the shaft from a stationary cup 19, mountedson a stationary cap 20, and admitting oil to the interior of the sleeve through perforations'21 therein. Ihe steam is supplied to this bearing through a pipe 16, which communicates with the ,steamways 13 through an elbow-pipe 161.

The bearings l2 and 18 are provided with the escapeopenings 13b.

22 is a drivingsleeve for the fan 23, which sleeve has a gear 25, whereby it may be ro-v IOO n tated in either directio'n.

Y The steam-pipe -16a is carried b`y the sleeve.

26 is a ilange on the sleeve 22 and'having the annular steam-space 27, with which the steam-pipe 16 communicates. f

28 is a circular cap which forms a cover for the chamber 27, and this `cap "is stationary,

While the sleeve itself maybe rotated in either direction. ders 26, Which are adapted to embrace the edges of the circular cap 28.

29 is a stationary stea1n-pipe,Which istapped through the circular cap 28 and supplies steam to the annular chamber 27, from whence the steam escapes through the-pipe 16* to thev bearing 18.l It Will be observed that this vpermits therotation of the steam-pipe-ove'r theV Secondb'earn g,'wh'ile :the shaft is kept warmed by 'the steam in the annular 'chamber 27 ,and
